When I hold my L-rods over a line or perimeter and stay stationary, I observe them constantly moving back and forth. Their connected, or attached, and following some sort of wave. This wave varies in frequency and strength. Never is it stationary! Only our observation makes people believe its constant, when it's not. The known non contact forces are Gravity, Magnetism, Static Elrctricity. The strength of the Magnetic and Electrostatic forces varies under diffrent conditions, and possibly show diffrent results between diffrent people. Dowsing rods attach to follow the wave. There is no alignment! Why they attach? Not sure..
